This wonderful set of go equipment was refurbished in our Colorado workshop.
The stones are size 38 slate & shell. They have been cleaned per our Care Instructions. As you can see from the photos, the white pieces are Mexican clamshell about 10.7mm thick, with a variety of grades but mostly Snow-grade. The black pieces are slate about 11.1mm thick. It is preferred that the black be slightly larger than the white, so that they look the same size when side-by-side on the board. In this case the black pieces are both wider and thicker.
The clamshell stones were washed, soaked in h2o2 for a week, rinsed with distilled water, dried, and buffed with iso-paraffin wax. The black stones were washed and rinsed with distilled water, but they have not been buffed with mineral oil so we leave that option to you.
The bowls have been lacquered on the bottom and on the interior, so they have a shiny black look that contrasts with the orange tone of the wood. The type of wood is unclear and it may have been colored. The bowls are a bit beyond XL size, and they fit the size 38 stones snugly. Each of the bowls is lined with a felt mat to cushion the stones. The bowls have not been refurbished, and they are old enough that they have shrunk slightly and caused the lids to not fit easily on top - forcing the lids into place would put a stress on the bowls.
This is a Vintage product.
